Distant Galaxies Resolve Observational Discrepancy

Making use of new simulations of the history of the universe, astronomers have resolved a distance measurement anomaly that also strengthens RTB’s cosmic creation model. The discrepancy lies in the fact that astronomers observe a much larger number of giant arcs (images of gravitationally lensed distant galaxies) than predicted by past simulations of the evolution of the universe. However, previous simulations did not include galaxies out to far-enough distances with high-enough resolution. New simulations rectifying these deficiencies show a much higher probability of lensing for distant galaxies (those with redshift greater than 2), resolving the discrepancy between predictions and observations. Consequently, RTB’s creation model, which relies on accurate distance measurements, rests on firmer ground.
